Basic information
Sample name: Xiao Midi

Reference: Y. Pan, Q. Li, Y. Lin, and C. Jiang. 1991. Late Pleistocene fauna discovered in Yuanmou Basin, Yunnan. Acta Anthropologica Sinica 10(2):167-175 [ER 3818]
Geography
Country: China

State: Yunnan


Coordinate: 25.42° N, 102.07° E
Coordinate basis: estimated from map

Time interval: Late Pleistocene

Ma: 0.01654

Age basis: radiocarbon (uncalibrated)

Geography comments: said in the English abstract to be from "about 3 km. to the south west of the village of Reshuitangcun of Yuanmou county... on the top of Balan mountain"
there is a Reshuitangcun in Yunnan, but it's in Yongde County, and there's apparently no Balan Mountain or Balanshan
the Chinese text says the site was discovered by farmers from Shuishuikuo Village and was in Liangzi Fissure Cave in Xiaomidi, Xishan Mountain, but it also says it is 3 km SW of Rehuihu Village in Longquan Township, Yuanma District, on the north side of Paran Mountain
there is a Xiaomidi immediately to the southeast of Yuanmou County and none of these other place names is of any help, so I assume this Xiaomidi is the location
there is one radiocarbon date on bone of 16,540 +/- 1470 BP

Environment
Lithology: siliciclastic (mixed)

Taphonomic context: cave,fissure fill

Habitat comments: "cave-fissure deposit... redbrown silts, clayey soils and includes some breccia and lesser lime nodules"
possibly "related to human activity although human fossils had not been recovered in the site" and there are apparently no artefacts
the translated Chinese text regarding the lithology isn't interpretable

Methods
Life forms: carnivores,ungulates

Sample size: 27 specimens

Sampling comments: rodents including Hystrix subcristata are present, but not enumerated
